Wetback vs Dryback firetube boiler design

The dryback boiler reversal chamber has a rear wall that is lined, or jacketed with refractory, which passes combustion gasses from the furnace to multiple tube sheets and reflects burner heat, resulting in exterior radiation losses. The dry back boiler design uses a common rear tube sheet and features convenient fire-side and water-side access.

Excessive Cyclic Operations in Firetube Boilers

the tube leaks of firetube boilers in the 1950s. This report recommended the use of a fillet weld on the hot pass of the flues/fire tubes to reduce hoop stress caused by cyclic operations and to provide a heat sink to remove heat stress from the end of the tube extending out from the tube sheet.

What Causes Boiler Tube Leaks | Boiler Tubes | ChemREADY

Reasons Why Boilers Leak: 1. Tube Corrosion. Corrosion and the breakdown of system components are the leading causes for boiler leaks. While this can theoretically happen anywhere within the boiler, corrosion in the tubes themselves is the most direct cause of leaks. Tubes can become corroded over time due to oxygen pitting.
